The invention provides a battery safety monitoring system and method based on a safety valve, and the system comprises the safety valve, a battery management system, and an external power supply which is used for supplying power to the safety valve and the battery management system. The safety valve comprises a fixing part, a gland part, a liquid absorption expansion part and a heating part, a discharge channel is formed in the fixing part, and the discharge channel is opened and closed through the gland part; the imbibition expansion part is arranged between the gland part and the fixing part; in a normal mode, the gland part closes the discharge channel; in the liquid discharge working mode, the gland part is ejected open through the liquid absorption expansion part which absorbs liquid and expands, and the discharge channel is opened; the imbibition expansion part is dried through the heating part; in the pressure-relief explosion-proof working mode, the gland part is opened through gas ejection, and the discharge channel is opened; the safety valve is connected with a battery management system through a magnetic switch, the electric heating component and an external power source form a heating loop, and on-off of the heating loop is controlled through the battery management system.
本发明提供了一种基于安全阀的电池安全监测系统及方法,其中,系统包括安全阀、电池管理系统以及用于对安全阀和电池管理系统进行供电的外接电源;安全阀包括固定部件、压盖部件、吸液膨胀部件和加热部件,固定部件上设有排放通道,排放通道通过压盖部件打开和闭合;吸液膨胀部件设置在压盖部件和固定部件之间;在正常模式下,压盖部件将排放通道闭合;在排液工作模式下,压盖部件通过吸液膨胀的吸液膨胀部件顶开,排放通道被打开;吸液膨胀部件通过加热部件干燥;在泄压防爆工作模式下,压盖部件通过气体顶开,排放通道被打开;安全阀通过磁性开关与电池管理系统连接,电热部件与外接电源形成加热回路,加热回路通过电池管理系统控制通断。
